Auditory elevation localisation was investigated under conditions of illusory self-rotation (i.e., vection) induced by movement of wide-field visual stimuli around participants' z-axes. Contrary to previous findings which suggest that auditory cues to sound-source elevation are discounted during vection, we found little evidence that vection affects judgements of source elevation. Our results indicate that the percept of auditory space during vection is generally consistent with the available head-centered auditory cues to source elevation. Auditory information about the head-centered location of a source appears to be integrated, without modification, with visual information about head motion to determine the perceived exocentric location of the source.
在由围绕参与者z轴的宽视野视觉刺激运动所诱发的虚幻自我旋转(即视动)条件下,对听觉高度定位进行了研究。与之前的研究结果相反,之前的研究表明在视动过程中声源高度的听觉线索会被忽略,而我们几乎没有发现证据表明视动会影响声源高度的判断。我们的结果表明,视动过程中听觉空间的感知通常与可用的以头部为中心的声源高度听觉线索一致。关于声源以头部为中心位置的听觉信息似乎未经修改就与关于头部运动的视觉信息整合在一起,以确定声源的感知外心位置。
